On the seventh day of abortion, the vague pain in the abdomen is mainly considered for two reasons: the first is abdominal pain related to abortion, such as poor uterine recuperation or abdominal pain caused by uterine cavity infection. In this case, there is mostly prolonged vaginal bleeding, the color is bright red, the abdomen is falling or accompanied by fever, through the gynecological examination, gynecological ultrasound, blood routine, C-reactive protein and other related tests can be clearly diagnosed. If it is poor uterine regrowth, it can be treated with uterotonin or motherwort; if it is infection, it must be treated with a sufficient course of antibiotics. The second is to consider abdominal pain not related to abortion, such as abdominal pain caused by intestinal diseases or urinary diseases, which is mostly accompanied by abnormalities of stool or urine, and relevant examinations should be done according to the specific manifestations of the patient.
